With that light original pattern barrel I bet it weighs less than your beans.
I first laid hands and eyes in person on an SP-1 in 1972. I got to fire 10 rounds out of it and thought it was da-bomb. I was thinking that Vit's looked exactly like that one, your serial number look up just validated my impression. Took me until 1994 to actually get around to buying an AR15.
